Small-but-happy win: If you tell ChatGPT not to use em-dashes in your custom instructions, it finally does what it's supposed to do!
GPT-5.1 is now available in the API. Pricing is the same as GPT-5. We are also releasing gpt-5.1-codex and gpt-5.1-codex-mini in the API, specialized for long-running coding tasks. Prompt caching now lasts up to 24 hours! Updated evals in our blog post.

We’re fighting this overreach on user privacy. As has mentioned before, we need a new form of privilege - AI privilege - given some of the kinds of conversations people are having with these tools today. Fittingly, Nils Gilman published an op-ed in the NYT discussing AI

GPT-5.1 is out! It's a nice upgrade. I particularly like the improvements in instruction following, and the adaptive thinking. The intelligence and style improvements are good too.
Also, we've made it easier to customize ChatGPT. You can pick from presets (Default, Friendly, Efficient, Professional, Candid, or Quirky) or tune it yourself.

Some thoughts on the whole 'OpenAI loan guarantee" situation. 1. First, for context: this issue began a few days ago when openai CFO Sarah Friar publicly floated the idea of the federal government providing a loan guarantee for the development of ai data centers. 2. I, and

I would like to clarify a few things. First, the obvious one: we do not have or want government guarantees for OpenAI datacenters. We believe that governments should not pick winners or losers, and that taxpayers should not bail out companies that make bad business decisions or
A thing often in common among great startup investors, founders, and researchers: Trading making a lot of small mistakes in exchange for getting a few giant wins. (Surprisingly many people seem to prefer a few big mistakes in exchange for a lot of small wins.)
Codex has transformed how OpenAI builds over the last few months. Have some great upcoming models too. Amazing work by the team!
i helped turn the thing you left for dead into what should be the largest non-profit ever. you know as well as anyone a structure like what openai has now is required to make that happen.

If you want to use more Codex after you hit your subscription limits, you can now buy credits as needed. This is something we expect to do for compute-intensive features; it will let us keep subscription prices low for most users and let the rest of you go wild.

You’ve asked for more flexible ways to get more Codex usage: Introducing credits for Codex on ChatGPT Plus and Pro. Credits give you more usage beyond what’s included in your plan, kicking in when you hit limits. As a bonus, we also reset Codex rate limits for everyone. Enjoy!
I love the way Tibo and team are so methodically going through every inch of the system to try to track down user feedback.

Codex is so good, and is going to get so amazing. I am having a hard time imagining what creating software at the end of 2026 is going to look like.
One of the most fun parts of OpenAI is watching people here level up so fast and do such excellent work. We are operating at a high level across many different disciplines and many of the people doing it have never done it before, and joined us at the beginning of their career.
Excited to partner with AMD to use their chips to serve our users! This is all incremental to our work with NVIDIA (and we plan to increase our NVIDIA purchasing over time). The world needs much more compute...

Excited to launch Sora 2! Video models have come a long way; this is a tremendous research achievement. Sora is also the most fun I've had with a new product in a long time. The iOS app is available in the App Store in the US and Canada; we will expand quickly.
I did not expect such fun dynamics to emerge from being able to "put yourself and your friends in videos" but I encourage you to check it out! ChatGPT Pro subscribers can generate with Sora 2 Pro. Longer post coming in a minute.
